Specification. of Letters Patent.

Patented Jan. 2,1912.

Application led November 17, 1909. Serial No. 528,538.

To all 'whom it may concern.'

Be it known that I, HERMAN FAULKNER, of Salt Lake City, in the county of Salt Lake and State of Utah, have invented certain new and useful Improvements in Photographic A paratus; and I do hereby declare the fol owing to be a full, clear, and exact description of the invention, such as will enable others skilled in the 'art to which* it appertains to make and use the same.

This invention relates to improvements 1n photographic plate changing mechanism for taking moving ictures and continuous projection thereof y the aid of photographic )lates and more particularly to means for handling and progressively feedino' photograppic plates, cut films or other pil te materia One object ofthe invention is to rovide a machine ofthe character describe( which shall be adaptable for leeflinfy plates progressively in quick succession or making or for projecting so called moving pictures by the aid of hotographic plates or cut films, or for exhiliitirig` in more or less rapid suceessiomprints, plates or cards.

A further objecty is to construct the machine insuch manner that it can be adapted for use in feeding automatically various quantitiesof plates,l films or prints, conveying the same intermittingly and succes-- sively from one magazine to another and back again, so that tiey may thus be caused to travel in a continuous circuit'through the magazines and be exposed or subjected to the influence of light during their transit from one maffazine to another.

A further dbjeet is to so construct the machine insuch manner that it can be adapted for use in feeding a limited number of plates films or rints, conveying the required number o the same from one magazine to another, and be automaticall operated to reverse the feeding of the p ates in the magazines, conveying tie same plates in reverse order back to their original positions in the starting magazine,and that the machine may automatically make these changes and cause the plates to travel in seesaw fashion.'

A further object is to so construct a ina-f chine of the character s ecified that it can be made tov feed or handle the plates either' in see-saw fashion or continuousl inthe same direction and to provide e ectricall means for automatically reversing the operation of the feeding means.

A further object is to so construct a machine of the character described that it may be accurate, rigid and ellective in its movements, displaying or feeding plates in like manner from eittlier side of the machine,- thus projecting a limited number of plates orcut films from both sidesV of one. source of light on two screens at the same time, so that an almost unlimited number of changes may be shown on two screens by one source of light. with aV limited number of slides within the magazines. v

Afurther object is to so construct a machine for feeding plates or cut films, that the machine can be o erated in series of two or more machines o its kind to enable duplex or multiplex projection, and when two or more plates are to be projected on the screen in coincident positions upon the screen and a'series of machines are-operating or projecting images intermittinglyl from each iead or source of light,-with tliepictures arranged iii one machine so that one will project the even numbers of the series and the other the odd numbers of tliesanie series of animated pictures, the result being du lexprojection.

X further object is to so construct the machine that it shall be adaptable for feeding a limited number of plates progressively and, by the employment of a metal or dumm late, to automatically reverse thel fee` and change the direction of travel of the contents of the magazines,-thus causing a seiies of pictures to travel in one direction when projected on the screen (by multi lex projecting) and seen to build up an a vertisement or animated image, while if the machines be reversed, the pictures will move in the opposite direction and produce a tearin 1r down eil'ect.

With these an( other objects in view the invention consists in certain novel features of construction and combinations of parte ns hereinafter set forth and pointed out in the claims.

' In the accompanying dra\vings,-Figures 1 and@ are views which, when read together, constitute a plan of a machine embodying my invcntion,-Fig. 1 embracing the. feedl ing mechanism and magazines and Fig. 2 showing the means whereby power is ap- "plied for driving the mechanism. Figs. 3

and 4 constitute a rear elevation of the machine,-the front elevation diilering therefrom only in thatthe driving eccentric and parts operated thereby would appear in reverse positions to those shown in F 3 and 4 and that the front elevation would not show the power gear feeding devices for the magazine belt conveyers. Fig. 5 is a rear elevation showing only such arts as appear outside of the line A- of Fig. 1. Fig. 6 is a view in elevation showing only such parts as appear inside of the line A- of Fig. 1. Fig. 7 is a left end elevation showing parts contained in the machine to the left of the axis of the light. Fig.' S is an end elevation showing the driving mechanism and those parts contained in the machine to the right of the axis of light. Fig. 9 is a horizontal cross-section on the line B-B of Fig. 3,-tliis section giving an unobstructed view of the path of travel of the plates as well as the positions of the parts of the shuttles when feeding plates in a continuous circuit.. Fig. 10 is a iorizont-al cross-section of the base of the machine on the line C-C of Fig. 3, showing the positions and connections of the automatic reversing fin ers and pitmen as they appear on the mac iine when not engaged and when the circuit of the electrical devices is open. Fig. 11 is a front elevation of a shuttle when operated as a propelling shuttle,-the shifting frame 13--11--9 being omitted that an unobstructed view of the shuttle proper may be had. Fig. 12 is an outer end elevation of the shuttle when operated as a ropelling shuttle and embracing the parts o the shifting frame 13-11-9 as sl own in Figs. 3 and 5, and Fig. 13 is a horizontal cross-seetion of the shuttle on the line B Fig. 3. Fig. 14 is a diagrammaticaliview showing the circuit of the solenoid I and contact brushes 81.

The entire mechanism, with the exception of the objective lenses (not shown) may bc employed in a light tight casing. However, where a suitable lamp house 79 is placed about the light within the machine, as shown in Fig. 1, the machine may operate for projecting pictures. By this arrangement, overheating of the plates and the machine will be prevented and if the machine be used as a magazine plate camera, it will be necessarily in a light tight box, with the exec tion of the camera lens.

T e machine coinpreliends an automatic plate feeding structure comprising a frame carrying two tra )ezoidal magazines Systematically place with respect to each other; means for conveyin the plates through the ma azincs paral el with each other and paral el to the planes of raceways; two parallel raceways at right angles to the inner ends of the magazines and serving as guides for the plates during their travel in train fashion from one magazine to the other at both front and rear of said magazines; two windows or openings, one in each racewa-y, at which the plates are exposed or exhibited; means for conveying the plates from the delivery ends of thel magazines through the riiceways and accurately centering theni at the windows, and means for conveying the plates from the raceways into the receiving ends of the magazines. rlhe machine also compreliends the reversing of the feeding mechanisin, which will cause the reverse action or' those parts which feed the plates within the magazines as well as within the raceways and thereby reverse the direction of travel of the plates in the raceways and magazines; two outwardly tilting magazine walls 'that will adjust themselves to conform to the travel of the plates and thus reverse the trapezoidal positions of the magazines; two pairs of interchangeable and reversible shuttles that are so placed that when acted upon, reverse the feeding of the plates from the ends of the magazines into the raceways; two pairs of reversible magazine belt feeding mechanisms that cont-rol the magazine belts and when acted upon, reverse the direction of belt action within the magazines. Three vibrating pitmen and adjustable tap )et fingers thereon are provided to operate in the path of the reverse levers of the shuttle and ratchet gear mechanism, at

such time as the circuit of the electrical def vices is closed by the feedino` of a dummy metal plate to the axis of the window within a race-way. Two pairs of spring con taets or brushes are providedadjacent to the raceway windows for the purpose of forming by coperation with a dummy metal plate, circuit closing means.

In the construction of the frame work of the machine, I employ two pairs of vertical front and rear frames, each comprising a series of tive uprights 16 and 16* and horizontal u per and lower longitudinal beams 17 an 17l connecting the uprights, the two frames thus formed being bound together by bolts passing through the upriglits 16 and 16, and the horizontal beams 17 and 17 at their crossings. Between each of the frames are spacers or washers 17b to hold the frames apart slightly. The front and rear frames are connected by cross beams or braces 2O as shown in Figs. 1 2, 7 and 8. The two intermediate uprights 16 and 16*` of the respective frames are so spaced apart that windows or o enings E and F are formed between tieni and between the central and end iiprights 16 and 16* of the respective frames, two horizontal magazines G, G, are disposed transversely of the frame work and these magazines communicate at both ends with raceways H, H, through which plates llt) are to be passed from. one magazine to the other and presented, during such passage, at the windows or openings E and F as will be more fully hereinafter explained.

Each magazine G comprises side walls 23 and 24 and can be made trapezoidal in shape by pivotally mounting the outer sidewall 23 of each machine as shown at 26. The object of the trapezoidal shape of the magazines and the tilting outer wall is to provide a wider mouth at the ends where plates are being received than at the delivery ends of the magazines, and the tilting outside walls 23 of the magazines allow the automatic reversal of this by the plates, accordiiig to the direction in which the plates are moving. The central pivot hinge 26 of. the outer magazine wall 23 allows the receiving end of the magazine to be automati cally changed to a delivery end when the feeding of the plates in the machine is re` versed, and by this change, the plates will not wedge at the end of the magazine when the operation of the feeding devices is being reversed. The tilting side wall 23 of the magazine permits a free and proper position of the plates at the end of the magazine whether they are being received from the raceways or delivered thereto. The two magazines are identical in construction and hence a detailed description of one will suiice for both.

Each magazine comprises a floor 21, top or ceiling 22 and sides 23 and 24. The side or wall 23 is hinged at the center of the magazine by means of a sliding bolt 26 passino through a plate 25 and this construction will permit the said wall 23 to tip either in or out as the case may be and forni the trapezoidal shape of the magazine when the latter is filled with plates,- it being understood that when the machine is operated to pass plates in front of the windows E and' F in the two raceways H and to malte the travel of plates to follow a continuous circuit through the maA azines and raceways, a sufiicient number o plates should be employed to fill both magazines so that when a plate is discharged from one end of a magazine. another plate will enter the opposite end of the saine magazine and thus keep the latter filled. The outer wall 23 is made with notches 23* at its corners to allow rollers on the shuttles to freely pass. Both ends of the outer wall 23 are the saine in construction and are not connected to any part of the machine but are supported and held in place solely by the pin 26 engaging the plate 25. Furthermore, the wall 23 of each magazine forms a door which enables the changing of the plates into the magazines and is so mounted that it may be removed by depressing the hinge pins 26 toward the center against the resistance of springs 26l and out of contact with the plates 25. The inner wall 24 of each magazine is bolted to a guideplate 28 resting on a horizontal angle piece 29 of the adjacent raceway and at right angles to the plane of said raceway. The walls 24 are somewhat shorter than the walls 23 and thus form small gateways or openingsl 24 communicating with the raceways. The floor 21 and ceiling 22 of each magazine connect with the angle piece 2t) bv resting upon a cross-plate 30 bolted to said angle piece. The ends of the floor plates 21 and the ceiling )lates 22 intermesh slightly with the angle pieces 29 of the raceways and provide for a free movement ot' conveying belts 3l in passing in and out of the ends of the magazines, as shown in Fig. t).

As shown iii Fig. tt, the two longitudinal angle raeeway pieces 2S) are secured to uprights 16 with their inside members pi'ojecting toward the axis ot' the machine and forming floors and ceilings for the raceways H, while the vertical members ot' said angle pieces 2) forni the outer walls ot' said raceways. rlhe upper and lower angle pieces 29 are identical in construction and, with the guide plates 28 (Fig. 9) forni the guideways or raceways H connecting thc ends ot' thc magazines. Raceway tension springs S0 arc secured to the plates 28 and beal against the outer walls of the raeeways so as to press the plates against. said outer walls when said plates travel through the raeeway and become disposed between said springs 80 and the outer wall of the raceway,-tlie plates being in this manner prevented from vibration.

The vertical member of each angle piece or stri i 2!) is slotted where the same passes t-lie end of a magazine to facilitate the movement or travel of shuttles pawls 5 and rollers 7 and permit the saine to properly engage the plates for feeding the latter. lhe plates are fed from the magazines to the raceways and made to bear against the outer wall or side of the angle strips or pieces 25h-said plates being fed through the magazines (l by frictional contact with two eonveyer belts 31 as shown in Figs. (t and T. 'lhese belts pass over rollers 32 and 33 havingl their journals mounted in hangers B5 and the latter may be secured to the angle pieces 29. It will be observed in Figs. (t, 'i' and 9 that the belts B1 eiitei the magazines at the ends and pass over both floor 2l and ceiling 22 at their juncture with the angle strips or pieces 20. Idlcrs 34 are provided for the belts 31 and have their journals mounted in bearings 37 secured to brackets 3G supliorted by the floor and ceiling membersl of the magazines. It. is apparent that by adjusting the idlers 34 in the brackets 36, the belts 31 may be tightened or loesened as occasion may require.

etween the lamp in the center of the llO machine and the windows E and F, light condensers 78-78 are located and supported in any suitable manner.

It has been hereinbefore explained that the plates are fed from a magazine to a raceway and the mechanism wil now be described by means of which the pliites aie moved successively to a raceway, exposed at the windows E and F therein and then moved to the receiving end of the other magazine to be discharged tliereiiito. conveyed therethrough and then passed through the other raceway. exposed at the window tliei'ein and finally returned to the receiving end of the first magazine. For moving the )lates forwardly in the raeeways as said piates enter the latter from a magazine, I employ reciprocating shuttles 1 and Q adapted to engage the rear edges of the )lates only long enough for each rear edge o n plate to move slightly beyond the inner face of the inner wiill 24 of the inagazine,-tlie plate being iiiipelled the remainingdistance through the raceway to the receiving end of the other magazine by the advancing edge of the next succeeding plate and the latter being iinpelled by the next succeeding stroke of the sinne shuttle. The mechanisms at both front and rear of the machine are the same, thus rendering a detailed description of both unncccssanv, and as the )lates are discharged from one end and received by the other end of cach magazine, the connections for 0peratiiig the devices which cause the )assage of plates through the raceways will )c such that the action of the shuttles 1 and 2 at one side of the machine will be exactly the same as the shuttles 1l and 2 at diainetrically o i posite corners of the plate circuit at the other side of the iiiiiclune. When the machine is in operation, an odd nuiiiber of )lates (three when as shown in Fig. 6) will be in cach raceway. The sweep of the shuttles (Figs. 3 and 4) will be the same as the throw oi' sweep of eccentric 40-41 and connecting arms 19.

Strips or guides 3S having grooves SFigs. 3, 7 and l2) forming hearings foi' ba ls 1, are provided for the accommodation of the shuttles 1 and 2. These strips or guides B8 are attached to standards lt of the outer framework and their grooved portions disposed opposite each other above and below the shuttles. Each shuttle comprises two members or grooved ruide plates 1", 1b (Fig. l1) connected toget ier by strips 3 and 3* bolted near their ends and having their grooves disposed to accommodate the balls 1, which latter are located between said strips 38 and the guide plates 1". At each end of each member or strip 1* of the shuttle. a plate or clip 30 is secured to retain the balls 1c in place. The shuttles are connected with each other by means of two horizontal beams 14 which are adjustably connected with the strips 3 of the shuttles as shown in Fig. 5 so that said shuttles can be adjusted with respect to each other and to properly [liropel the plates and center them at the wincows EI Arms or links 4 are pivotally inter nosed between the bearing blocks or mem ers 1" of the shuttle with their journals mounted in the ends of the blocks near the standards 3* (Fig. 13) and to these arms a pawl plate 5 is attached, as shown in Fig. 11. The plate 5 is provided with pawls or projections 5 (Figs. 12 and 13) to engage the rear edges of the )lates as they come from the magazines when the machine is operating. rlhe pawls 5 are thrust inward by meansof flat springs 10 which bear against the arms 4, and to )revent the pawls o plate 5 entering too far into the mouth of a magazine, governors or stop pins 12 (Figs. 11 and 13) are employed to adjust and check the sweep of arms 4./ Thus t ie )awls 5'* of plate 5 may be allowed to exten into a magazine just the proper distance to carry out at one time, the plate to be iinpelled into the raceway. In each shuttle, I employ a pair of feed rollers 7 supnorted by plates 6 which are connected with each other by a pin or bolt 8. as shown in Figs. 11, 12 and 13. The plates 6 are freely mounted between the bearing blocks or members 1h bv means of suitable pins or headed screws. The feed rollers 7 will be thrust into the mouth of the receivin end of a magazine when the shuttle is receiving plates andaafter said shuttle has been converted into a roller feeder, by pressure of springs 10a secured to the strip 3 of the shuttle, on pin 8 secured to the plates carrying said feed roller 7. See Fie. t). It will be understood that each shuttle is convertible; that is, the iictioii and work of each shuttle may be changed by means of reversing devices so that the pawls 5' may be in position to iiiipel plates out of the mouth of the magazine and the rollers in said shuttle be held out of action or out of the ath of said plates, or may be adjusted to orm a roller feeder to discharge plates into the other magazine and have its pawls 5 out of o rative position. The results above described are attained by means of a shifting fraaie comprising members 9, 11, 11 and 13,-said frame or shifting device entering and being connected with each Vair of shuttles (as shown in Figs.3,5 and9) in such manner that when the shuttles 1 and 1* are iinpelling plates out into the raceway, the shuttles 2 and 2 are feeding the incoming )lates at the opposite ends of their strokes, into the mouths of the other magazines. It. is therefore ap )arent that no single shuttle can have iii action both the pawls 5 and the feed rollers 7 at the same time, but that either the pawls are in operative position and the rollers 7 out of operative position or vice versa. Furthermore, as shown in Fig. 9, the shuttles 1 and l stand with their pawls in action and their rollers out of action. Shuttles 2 and 2 are shown in Fig. 9 as converted to roller feed shuttles with the rollers adapted to feed the incoming plates into a magazine and out of the path of succeeding plates in the raeeway. F r'om an insiection of Fig. 9, it will be observed that s iuttles 1 and l are impellin" shuttles while shuttles 2 and 2^ are adjusted` to form roller feed shuttles. I will therefore explain the operation of the shuttles as adjusted in Fig. 9 of the drawings and later explain the means employed for reversing and thus converting the work and action of said shuttles. As one of the shuttles (say the shuttle 1) at its forward sweep has moved a plate by means of the pawls 5 toward the opposite magazine, the shuttle 9. has also moved forwardlv in advance of the incoming or moving plate and serves the purpose at this time, of holding the contents of the magazine far enough into the latter to keep a clear path into the magazine for the advancing plate by means of the projecting roller 7 acting or resting against the face of the plate which has been previously received at the receiving end of the magazine. lVith the machine as shown in Fig. 9, shuttles l and 1'* are impelling platesl by means of pawls 5 and shuttles :2 and 2^ are receiving plates. The machine as shown in Fig. 9 will cause the plates to travel in such manner as to ma'ke a complete circuit, said plates leaving one end of one magazine, passing through a raceway and entering the other magazine, through which they will travel and-)enter the other raceway and, after passing through the latter enter the opposite end of the first mentioned magazine.

The various shuttles are the saine in construction and can be reversed automatically1 as to their action on the plates by means of devices which will now be explained.

It may be assumed that there are dummy metal plates K within each magazine and that these, together with the photogra hic plates, will fill the magazine. The maciiine 1s then operated in the manner indicated in Fig. 9 of the drawings. The travel of the plates would be in a continuous circuit through the magazines G and raceways H until such time as a dummy metal plate reaches a position in the racewav in front of a window E (or F), when said zdummy plate will make contact with contact springs or brushes 81. Two such brushes 81 are employed in front of each window E and F and these brushes are included in a normally open circuit with a includes the solenoid, thereby energizing the latter as shown in Fig. 1:4. The cote of the solenoid is connected with a bar or pitman (3(5, the latter being connected with and adapted to'eause the operation of devices which effect the reversal of the shuttle action, as hereinafter explained. The re 'ersal ot' the action of the shuttles is to be obtained at the instant the forward edge of the metal plate comes into contact with the brushes 8l in the raceway, and means are also provided. under the control of the metal dummy plate, and its cooperating electrically controlled devices, for reversing the feeding of ther plates in the magazines at the same instant that. the actions of the shuttles are reversed. By converting shuttles l and 1" to form roller shuttles and converting shuttles 2 and 2" to form propelling or feeding shuttles, the rollers 7 of the shuttles l and l will be forced inward and the pawls 5 moved out of the path of the plate travel and thus the shuttles l and 1a are n0 longer propelling but are roller or receiving shuttles. At the same instant that the shuttles 1 and l are transformed into receiving shuttles, the shuttles 2 and 2 are converted into feeding shuttles.

The shifting means for reversing the action of the shuttles comprises members 15-15, 13-11-11-9 and 9", shown in Figs. 3 and The tappet levers 15 and 15 are for the purpose of operating the shuttle shifting devices and these tappet levers are actuated b v engagement with fingers 76 and 76 adjustably mounted on the shaft 73. Shaft 73 is mounted in hangers 68, there being two such shafts, one at each side of the machine and each of said shafts is provided with the fingers 76 and 7G disposed below the respective windows E and F. The shafts 73 are connected and operated in unison so that each pair of fingers on each side of the. machine may move inwardly to engage the tappet levers 15 or 15 of the shifting frames which connect the shuttles. When the shafts 73 have been moved so that the fingers thereon will become disposed in t-he path of the tappet levers, one orthe other of said tappet levers will engage one of the fingers as the connected shuttles move in the same direction in the raceways and cause the tappet levers which thus engage fingers on the shafts 73 to -be oscillated and thereby transmit motion to' the bars 13 and consequently to the members 11 on the shuttles and the wedges 9 to etlect the reversal of the action of the shuttles. The solenoid hereinbefore referred to is connected through the medium of the pitman G6 with an arm ('7 on one of the shafts 73 for oscilla-ting the latter. This shaft is also provided with an arm 67 and the latter is connected with the other shaft 7 3 for transmitting motion to the latter by means of devices which will now be described.

An arm 72 is secured to the framework at. one end thereof and to this arm a lever 71 is pivotally connected between its ends. One end of the lever 71 is connected by means of a rod or pitman 70 with the arm 67 on one of the shafts7 3, while the other arm of the lever 7l is connected by means of a rod or pitman 70" with an arm 69 on the other shaft 73. From this construction it is apparent that when the solenoid is actuated, motion will be transmitted to both of the shafts 73 and that the pairs of fingers carried by these shafts below the respective windows E and F will be moved simultaneously to effect the reversing of the various shuttles simultaneously through the medium of the shifting devices hereinbefore described. lVith the arrangement of the devices as above described, the shuttles will be converted or changed in form just previous to the delivery of a metaldummy plate to the window E or F.

In order to reverse the direction of travel of the belts 31 which feed the plates through the magazines, simultaneously with the reversal of the action of the shuttles, I provide a shaft 75 provided near one end with an arm 74 dis osed under one arm of the lever 71 and this shaft is also provided with another arm 74 andwith arms 74". Then the shafts 73 are oscillated and the lever 71 is turned as above described, said lever will engage the arm 74 adjacent to it and cause the shaft 75 to be turned a sufficient distance to canse the arms thereon to become disposed in the path of tappet levers 54.

' These tappet levers are pivotally supported by arms 53 on a rod or pitman 52 and are connected with ratchet plates also supported by the arms 53 and carrying dogs 56 to engage ratchet wheels connected with the gearing 63 by means of which the belts 3l are driven. It is apparent that when the rod or pitman 52 is reciprocated, motion will be transmit-ted to the belt gearing and that this motion will be continuous in the same direction as long as one pawl 56 on each ratchet plate 55 is co erating with the gearing. It is apparent iowever that if the ratchet plates be so shifted as.to move the Eawls 56 out of operative relation with the elt gearing and move the awls 56 into o rative relation with sai gearing, the direction of travel of the magazine belts will be reversed and therefore the movement of the plates through the magazines will also be reversed. This reversal of travel of the ma azine belts will occur simultaneously with the reversal of the action of the shuttles, by reason of the operation of the shaft 75 to move the arms thereon in lp osition to e'ect the shifting of the ratchet mechanism of the belt driving means, such operation of the shaft being effected prim'arily by the action of the solenoid which operates the shafts 73 to effect the reversing of the shuttles when the circuit of said solenoid is closed by the a pearance of a metal dummy plate in -t 1e raceway between two contact brushes 81.

The form of shuttles being convertible and the feed belts in the magazines being reversible, it is apparent that the plates may be propelled from one magazine and by the aid of the metal dummy plate at the end of a series of photographie plates, when propelled to the window la, will close the circuit of .brushes 81 and the solenoid to operate the bar or pitman 66 and the devices connected therewith and controlled thereby, and thus return the series of plates to the starting magazine instead of carrying them through the complete circuit of the two magazines and raceways as previ- 'onslv described. Thus, plates may be made to aseo-saw or travel in zigzag fashion within the raceways. This is desirable where a limited number of plates may be omployed,-in which case it would be well to use a suitable spacer block or dummy to fill the portions of the magazines which have not been used bv the photographic plates. This spacer block should be just the ro )er size to prevent the plates being manlpu ated from tipping over or tilting too much in the magazines.

Having explained the purpose of the shifting or reversing devices of the machine, I will now explain what changes and manner of movements would take place should the bar or pitman 66 be actuated prior to the full sweep of the shuttles 1 and 1.

It will be understood from Figs. 1, 3, 5 and 9 of the drawings, that the shuttles 1 and 1 are adjusted to propel plates in the res ective magazines and have reached their full sweep, having propelled a plate entirely eut of the delivery end of each magazine and slightly beyond the edge of the inner wall thereof. In the event that the bar or pitman 66 (Figs. 1, 9 and 10) be drawn inward at atime .previous to the shuttles 1 and l having completed their stroke or at such time that the tappet levers 15 and 15 are outside of the line of action of the fingers 76 and 76a (Figs. 3, 5 and 9), the machine may obtain a reverse feed,-the following movements taking place: Starting with the arm or bar 66, it may be assumed that the same has been actuated manually or otherwise as the shuttles 1 and 1 are )ropelling a plate into the raceways and efore completing their strokes. The sha fts 78 and their fingers 76 and 76 will be drawn inward instantly and at the same time standards or arms 74 and 74 on the shaft 75 will be thrust toward the belt feed gears 63.

Now just before the shuttles have completed their sweeps toward the windows l] and F, the tappet levers on each side of the niachine will engage the fingers 76, and as the' shuttles and shifting frame move onward, the lever 15 will be forced back, giving an additional forward motion to the shiftinfY trames (comprising parts 13, 11 and 11 far enough to move the inclined faces 'of the sliding plates or members 9 within the sluittle frame of shuttles 2 and 2 and at. the lsaine time advancing sliding pliites 9 within llie shuttles 1 and 1. This action of the two pairs of sliding wedge lates 9 and 9 converts the shuttles as fo lows, prior to coinpleting the sweep of the shuttle frames. Il`he shuttles l and 1 have been changed from propelling shuttles to roller or receiving shuttles, while the shuttles 2 and 2 have been changed to propelling shuttles. '.i`hese changes take place in unison and to prevent the locking up of the machine, the feed mechanism for the magazine contents must be released and then reversed and this is accomplished by the action of the levei' T1 in its coperation with an arm 74 on the shaft 75 to shift the ratchet mechanism which actuates the feed belts31 in the magazines as previously explained. Thus it will he seen that the engagement of a lever 54 with a standard or arm 74 (Fig. 10) while the connecting rods 52 are moving ratchet arms 53 toward the source of power, ciiiiscs the plate 55 to release the pawls 56 from engagement with the ratchet wheels (33 and at the saine stroke of movement of the levers 54 and ratchet plates 55, the ratchet pawls 5G are made to bear against the ratchet wheels 63 of the conveyer belt gearing. 1Vhen the pawls 56 are engaging the wheels G3 the arms 53 are moved through connecting rods 52 by a cani 44 and its reciprocating cross-head 51 toward the left cud of the machine (see dotted lines in Figs. l and 9). The pawls 5G will give an intermittent motion to the wheels (i3 and belt gearing 32 in the direction indicated by arrows in Figs. 7 and 10. If the pawls 5G he enfraged with the wheels 63, said pawls vill ride over the teeth of said wheels as the arms 53 move to the left and at the next sweep of the cam 44, the cross-head 51 will l-ring back the arms 53 to positions shown in Figs. 1, 9 and 10 and in so moving, cause the pawls 5G to interinesh with the wheels ("l and actiiate the sinne and the gears 232 in the opposite direction to that indicated 'in Figs. 7 and 10. By the shifting of the pawls 56 and 5G, the gears (i3 und 32 will stand idle while the cam 44 is making onehalf revolution and during the other half revolution of the cam, the gearing will be actuated to begin the motion of the conveyer belts 31. It will be seen that th'e conf tents of the magazines G are not moved apireciably in any direct-ion while the shiftiiigiof ratchet mechanism and converting of the shuttles are taking place. lhe shuttle action as well as the feed of the conveyor belts 31 having been reversed, the plates within the raceways H will be moved so as to return the dummy metal plates in the raceways from their positions at E or F toward the magazine or magazines from which the metal plate or plates had been previously propelled, thus opening the electric circuit of the solenoid and releasing the bar or pitinan 6G and parts controlled thereby. For the intermittent nioven'ient of the plates, as in moving picture work, the machine may be operated to pass the plates at a window E or F at a rapid rate of speed without a great amount of vibration of thel machine or plates.

The shuttles 1 and 2 also l and 2 receive motion from the eccentrics 40 and 41 on a power shaft 42. The eccentric 41 (Figs. 2 and 4) is provided with a cross-head and with a link 19 pivotally connected with the shuttle 2 at 18 (Figs. 3 and 5) so that said link will reciprocate as the eccentric 41 is rotated by the shaft 42, thus furnishing a smooth reciprocating motion to the shuttles 1 and 2. The shuttles 1 and 2 are similarly connected with and receive motion from the shaft 42. Then power is applied (from any convenient source) to a gear 43 keyed to shaft 42, the cccentrics 40 and 41 wiil give reciprocating motion to the sluittles 1 and 2 and 1 and 2, The shaft 42 is supported by ball-bearing hangers 45 and in Fig. 2 a portion of said hangers is cut away to show the arrangement of shaft, cones and balls. In Figs. 2, 4 and S the cam or cccentric 44 and cross-head 51 are installed to operate the intermittent feed of the belt gearing 63 and 32.

1Vitli the construction and arrangement hereinbefore described, the feeding of the plates will be practically continuous, but fer taking or pro]ecting pictures as in moving picture work, the feed should be intermittent. For accomplishing this, the devices new to be described may be employed.

A disk 4G is secured to the power shaft 42 and provided on respective faces with escapeiiieiit pallets 47 and 4T". The` pallets are pivotally attatihed'to the disk -and are guided by links 5i, said pallets being normally maintained in proper position by means of springs 47". At the ends of the guide links, rubber butl'eis 5S for the plates, are located. A shaft. (51 is mounted between liars 59 secured to the parts 1T and (30. An escapement lug 49 is secured to the shaft Gt and provided with two rollers Lit-48" to cooperate with tlie pallets 47 and 47 on the disk 46. An arm is also secured to the shaft 61 and to this arm, a rod 50 is attached and is connected with any suitable timing device, not shown, for operating the escapeinent lug 49 to control the intermittent motion of the shaft 42, by the cooperation of the rollers iS-1455" with the pallets I7 and 47 on the disk 46. The escapeinent mechanisni thus formed for causing the intermittiiig rotation ot the power shaft, is designed to overcome vibration and snapping noise. The two rollers 4S and 48 on the lug 49 are preferably made of compressed fiber or leather to deaden the noise when the disk flies around and the two vibrating pallets strike the rollers. The butlers orcusliions 58 may also be. of hard leatliei to deaden the noise. The two tension spiings -t't'b at the center of the pallets overcome the force of the release :s well as to pull down the pallet that may not be engaged with the rollers 48 or 4 1 as the case may be.

It will be observed that the form of escapement above described permits the disk to make a complete revolution at each impulse or vibration of arm {iO-50.

lith my improvements, it will be seen that, owing to frequent changes of the feeding mechanism controlled by the electrical devices through the medium of the metal dummy plate, a limited number of advertisements may be made to appear more often and in less time than were the plates containing such advertisements caused to make the complete circuit through the machine.

Numerous slight changes might be made in the details of construction of my machine without departing from the spirit of my invention or limiting its scope and hence I do not wish to restrict myself to the precise dctails herein set forth.
